I did so. the situation improved significantly(though i still experience the bug occasionally).
however now there is something wrong on startup. i have to restart pulseaudio manually (it shows up in  task manager so im pretty sure it is running on startup).

i tried running it in debug mode to see if there was something obviously wrong with the logs
here's an excerpt:


...
E: alsa-sink.c: ALSA woke us up to write new data to the device, but there was actually nothing to write!
E: alsa-sink.c: Most likely this is a bug in the ALSA driver 'snd_hda_intel'. Please report this issue to the ALSA developers.
E: alsa-sink.c: We were woken up with POLLOUT set -- however a subsequent snd_pcm_avail() returned 0 or another value < min_avail.

there were several lags during the quoted period, though i was not able to pin it down to particular message.
(full log of the debug run attached)

hope this is of some use.
